A fresh batch of spy photos depicting the 2014 Mercedes-Benz GLA has arrived at our office.

The A-Class-based crossover is slowly starting to lose its camouflage as we get closer to an official reveal scheduled for September at the 2013 Frankfurt Motor Show. In these latest pics we get to see the GLA's standard and panoramic roofs, along with exterior mirrors and sections of the taillights. At the front there will be a prominent grille and sweptback headlights, while the interior is likely to mimic the A-Class'.

Engine lineup will be carried over from the hatchback which means the GLA will be offered with a variety of four-cylinder gasoline and diesel engines, together with a possible 2.0-liter, 4-cylinder turbo developing around 354 HP (260 kW) for the range-topping AMG model.
